Game server fails to start on Debian
prockallsyms opened this issue · 7 comments
Hi! So last night I gathered the relevant files from the repository, pwn3 website, and docker to use docker-compose to setup the repository. Running the docker-compose binary doesn't fail, however there is a problem with the setup scripts that causes the game server to fail to boot, and exit with code 139:

./PwnAdventure3Server: error while loading shared libraries: libssl.so.1.0.0: cannot open shared object file: No such file or directory
I fixed it. I'll make a resolution pull request. Although I'm not sure if it's going to work for other OSs.

did you execute the server on your host system?
I guess your permissions are now all screwed up, but at least it's working :D But if you want you could purge the whole docker stuff again and start fresh.
If the issue reappears you could do this troubleshooting:
docker exec -i -t pwnadventure3_game_1 /bin/bash to get a bash shell inside the container, then do:
cd /opt/pwn3/client/PwnAdventure3_Data/PwnAdventure3/PwnAdventure3/Binaries/Linux/
su pwn3
./PwnAdventure3Server
Does this also crash with a segfault? If it crashes can you install strace inside this container and then start the server (as pwn3) with strace ./PwnAdventure3Server
Whatever happens inside your docker container should just work.
You should not execute the client you placed next to the docker-compose.yml on your debian host system since this one is used while running the live game server.
It's better to make a copy instead. Could this be the reason for the permissions issues?
I suggest you download it all again and start from scratch.
Could you please provide the logs of the docker-compose up command?
Yeah. My host machine is down because of a partitioning error I made, but once I figure out how to fix it I'll post the logs.
This happens because pwn3 has no write access to /opt/pwn3/server/creds, there is a step in the master server shell script where it writes the creds in that file. Sending a pull request to fix this.
Got a shell in the docker container and ran it with strace, the tail end yielded the following:
